[specification] add semicolon to separate declarations

[mrodz]

print "hello"

([1, 2, 3])[0]

Is interpreted as:

• print
  • index
    • callable
      • "hello"
        • [1, 2, 3]
    • 0

It would be helpful to have an optional ; to separate declarations

print "hello";

([1, 2, 3])[0]

Resulting in:

• print
  • "hello"
• index
  • [1, 2, 3]
  • 0
